Many of us may be most familiar with infrared thermography from its least valuable (I’d argue) use — ghost hunting.
It serves many far more sophisticated purposes, though, than providing fodder for those shaky-camera paranormal TV shows — from assessing medical conditions to military reconnaissance, from finding missing children to sensing mood changes in humans.
And, no big surprise, dogs.
In the latest post on Dog Spies, her blog on Scientific American, Julie Hecht recounted a recent study at the Animal Behavior, Cognition and Welfare Research Group at the University of Lincoln in the UK.
Researchers found, through infrared thermography, that the ear temperature of dogs decreased (turning blue on the camera) when they were isolated, and warmed backed up (turning red) when they reunited with people.
It’s similar to findings in studies of human stress levels — except in humans it’s the nose, instead of the ears, that is the most common giveaway.
As Hecht explained, infrared thermography picks up changes in surface temperature. When frightened, stressed or placed in unfamiliar surroundings, blood rushes away from your extremities, in dogs and humans. They get cooler as your core gets warmer and ready to react to whatever threat may be ahead.
The tip of a scared person’s nose gets cooler in such situations, just as rat paws and tails have been shown to do in experiments. In rabbits and sheep, the ears are the most obvious indicator.
Stefanie Riemer and colleagues placed dogs for brief periods in an isolated and novel environment. As the researchers expected, thermographic images of the dogs in isolation showed their ear temperature increasing, then rising when they were reunited with people.
The study appears in the current issue of Physiology & Behavior.
Six dogs were included in the study, and several were found to be unsuitable for study because their fur was too dense to get a good reading.
It seems like a technology that could be put to good use when it comes to studying dogs, and in learning more about those with behavioral issues and what triggers them.
That seems to me a better pursuit than chasing ghosts who aren’t really bothering anybody. Non-invasive, physically, as it is, even infrared photography has the potential for being cruel.
In a study in Italy two years ago, 20 bank tellers who had been robbed at gunpoint were shown a series of faces — happy, neutral, angry, etc. On the fifth face, the researchers exposed them to a loud and unexpected blast, and recorded, thermographically, how the blood left the noses and face.
Half of the tellers had already been diagnosed with PTSD.
Whether the researchers ended up giving PTSD to the other half is not addressed in the study.

Nobody knows how Sissy did it, but we’d guess it was with her nose.
The miniature schnauzer ran away from home last Saturday, and showed up about four hours later and 20 blocks away — inside the Iowa hospital where her owner was recovering from cancer surgery.
Nancy Franck has been recovering at Mercy Medical Center in Cedar Rapids for two weeks, and apparently Sissy got tired of waiting for her to come home.
“She missed mom, that’s all I can tell you. She missed mom,” Franck said.
Hospital security snagged the dog after she entered through the automatic doors and began wandering through the lobby.
They called the number on Sissy’s ID tags and only then learned, from Franck’s husband, that Nancy was a patient in the hospital.
“I thought she just wanted to go someplace, but I didn’t know where. She’d never run away before,” said Dale Franck.
Hospital surveillance tapes show the dog entering, and making her way to the elevators, where — momentarily puzzled — she paused.
“She wanted to see her mom. She was on a mission, but she didn’t know which elevator to take,” Dale Franck told ABC 7 in Chicago.
Family members arrived at the hospital, and they were allowed to take Sissy to Nancy’s room for a visit.
According to the family, their home is about 15 to 20 blocks from the hospital. Sissy had never been there before, they said.

Pawlitically incorrect as it might be, I do permit my dog to stick his head out the car window from time to time.
While there are those who say that’s putting him, and particularly his eyes and ears, at risk, I can’t bring myself to forbid him from sticking his nose out the window. To ban him from that activity would be the equivalent of taking someone to an art museum and blindfolding them.
So when traveling at reasonable speeds, and once in a while traveling at unreasonable speeds, I power down the back window halfway to let Ace sniff in the surroundings for a minute or two, usually at his urging — as in, “If I keep smushing my greasy nose into this closed window, he will open it a bit.”
I, unsafe and risky as it is, love to see the dog head protruding from the car window, almost as much as dogs seem to enjoy sticking their heads out the window.
To me, the dog head protruding from a car window, while maybe not as iconic as that torch Lady Liberty holds up, is a symbol of freedom and possibilities and soaking up all life has to offer. I have even tried it myself, but I got something in my eye and no longer take part in that behavior. Ace still gets to, though, within limits.
Admitting that will probably bring some criticism my way, just as I’d expect this new ad from Volkswagen might take some heat.
The ad features more than 15 dogs — all hooked up to seat restraints, it is said — but still managing to get their heads out the car window, in some cases well out the window.
(If you’re wondering why some dogs appear to be in the driver’s seat, that’s because the ad was filmed in the UK, for the British market.)
Twenty-two dogs were involved in the filming of the ad, and none of them were equipped with doggy goggles.
Thus those dogs, like my dog, were exposed to the danger of dirt, rocks, dust and debris that could harm their eyes; or ear damage that can result from them flapping too fiercely in the wind; or the possibility of falling out of the window.
The ad makers, judging from this behind-the-scenes “making of” video (below) seemed to exercise care and take precautions with the dogs.
But I’d be interested in hearing what you think. Will the ad be viewed as putting dogs in danger, or letting dogs be dogs? Is it joyous, or worrisome, and do you think it’s going to sell many Volkswagens? As for me, I was too busy looking at the dogs to notice the cars at all.

60 Minutes looked at bomb-sniffing dogs in a report that, especially given last night’s other featured stories — on the Marathon bombing and the 9/11 Memorial — brought home not just how many lives they’ve saved in the military overseas, but how many more they might save here.
Reporter Lara Logan focused on the dogs of war, and the trainers that describe their canines as nearly infallible when it comes to detecting bombs.
But they’re not so infallible when explosive devices are planted after the dogs have made their sweeps, as apparently was the case at the Boston Marathon.
“Would an average police dog have found these bombs at the Boston Marathon …?” she asked trainer Mike Ritland.
“…Based on what I do know, yes,” Ritland said. “If dogs went through the areas where they were placed– you know, your average, certified police bomb dog should have found them. My thoughts are if these guys (the suspects) are paying close attention to these dogs, they’re waiting. And when the dogs leave, they bring it in, they hand– they infiltrate, essentially, they drop it right where it’s busy, and very soon after, it detonates.”
As the “60 Minutes” piece pointed out, since 9/11 dogs have been used more than ever because nothing is more effective in finding hidden bombs. Dogs in the employ of the military and FBI have sniffed out bombs, captured enemies, and one assisted Navy SEAL Team 6 when it took down Osama bin Laden. Much more of what they do, given the often secretive nature of their work, never becomes known.
“The best of them serve with U.S. Special Operations and they’re in a league of their own,” Logan noted. “It’s nearly impossible to get anyone to talk about them publicly because much of what they do is classified, but we were able to talk to the people who train them for this story. We took the opportunity to ask about what might have happened in Boston while getting a rare glimpse inside the secretive world of America’s most elite dogs.”
(One member of the “60 Minutes” team — in a segment not shown on the air but featured on 60minutesovertime.com — even volunteered to be chased down by a military dog in training in Texas. Producer Reuben Heyman-Kantor, in the video above, tried to outrun the dog, but was brought down quickly.)
In her interview with former Navy SEAL Ritland, who now finds and trains dogs for Special Operations and top tier units in the FBI, Logan asked, “What can these dogs do on the streets of America?”
“The very same thing that they do for our boys overseas in that they detect explosives– they are a fantastic deterrent– they use their nose to find, you know, people as well,” Ritland said.
“Everybody knows that dogs can smell better than humans but what they don’t realize is that if you and I walk into the kitchen and there’s a pot of beef stew on the counter, you and I smell beef stew. A dog smells potatoes, carrots, beef, onion, celery, gravy, flour. They smell each and every individual component of everything that’s in that beef stew. And they can separate everyone one of those. You can’t hide anything from them. It won’t work because you can’t fool a dog’s nose.”
Ritland now trains dogs on his 20-acre ranch in rural Cooper, Texas, runs the Warrior Dog Foundation for retired war dogs, and is the author of “Trident K9 Warriors: My Tale From the Training Ground to the Battlefield with Elite Navy SEAL Canines.”
Ritland says its important — amid these days of budget cuts — to remember what lifesavers the dogs can be, both in wars and at home.
In Afghanistan, according to the report, 42 dogs have been killed in action. They’ve become so effective that the enemy is singling them out. A Taliban commander told “60 Minutes” that on his last operation they were ordered to open fire on the American dogs first, and deal with the soldiers next.
Logan visited what she said was one of only three breeders in the U.S. who produce dogs — almost always the Belgian Malinois — for top tier military units.
She also interviewed Green Beret Chris Corbin who, along with his dog Ax, almost died on their final mission in Afghanistan.
Corbin said he missed a signal from the dog while searching for mines. Ax was alerting to Corbin’s foot, but Corbin realized it too late. He lost both his lower legs. Ax was not wounded. Both returned to duty.
Ax was at Corbin’s side during the interview, and rarely took his eyes off his former partner as he described their first reunion after the blast.
“I just said something simple. ‘Hey, where’s my boy at?’ and he stopped. He froze. He looked around. And he went into a panic until he found me and he jumped on my legs. Painful. Just– I was just happy to see him. I didn’t care how much it hurt.”

Bulldogs, pugs, and other short-of-snout breeds accounted for about half of the purebred dog deaths on airplanes in the past five years, the data shows.
Overall, 122 dog deaths — 108 of them purebreds — were reported between May 2005, when U.S. airlines were required to start disclosing them, and May 2010, the Transportation Department says.
All the dogs died while being shipped as cargo, as opposed to flying in the cabin.
English bulldogs accounted for the highest number, with 25 deaths. Second highest were pugs, 11 of which died. Seven golden retrievers, six French bulldogs and four American Staffordshire terriers died while flying as cargo in that period. And boxers, cockapoos, Pekingese and Pomeranians accounted for two deaths each.
You can see the full list here.
The Department of Transportation says dog owners should consult with veterinarians before putting their dogs on planes. It believes that the deaths represent a tiny percentage of the pets shipped on airlines.
Short-nose breeds — known as “brachycephalic” — in addition to being less tolerant of heat, have a skull formation that affects their airways, Dan Bandy, chairman of the Bulldog Club of America’s health committee, told the Associated Press.
“The way all dogs cool themselves is basically through respiration, either just panting or the action of breathing in or out, is a method of heat exchange for them,” Bandy said. “A dog that has a long snout or a long muzzle has more surface area within its nasal cavity for that heat exchange to take place. So breeds like labradors or collies or those types of dogs with the long muzzles have a more efficient cooling system.”
Bandy said that in addition to trying to cool themselves, dogs may also pant excessively in the cargo hold because of stress or excitement. But he believes dogs shouldn’t be given tranquilizers before flying because that makes them less able to manage their own cooling process. In addition, airlines generally do not want pets tranquilized, he added.
In all, 144 pet deaths were reported by airlines over the past five years, along with 55 injuries and 33 lost pets.

What would you name a dachshund, born deaf and blind, who counts on his nose to show him the way?
To Marcia Fishman, the answer was obvious: Rudolph.
After bouncing between four other homes, Rudolph was adopted by Fishman two years ago, and he’s gone on to become a visitor to elementary schools, and the subject of a children’s book.
“Rudolph’s Nose Knows,” written by Fishman, is about a blind and deaf dog teased by other dogs because he bumps into things. When he turns out to be the only one able to rescue a bird stuck in a hole, he becomes a hero.
As a team, Rudolph and Fishman visit schools around Detroit to help show kids that disabilities are surmountable, and that teasing — whether over a red nose or some other physical challenge — is a painful and misguided waste of time. Fishman hopes that Rudolph, the dachshund, can help teach children to accept others who might appear different from themselves.
Last week, they dropped in on more than 60 third-graders at McIntrye Elementary School in Southfield, according to the Detroit Free Press.
“Shut your eyes and hold your ears as tight as possible,” Fishman told the students. “Don’t feel sorry for Rudolph, he is a happy dog. But I want you to understand what he experiences every day of his life.”
Though he can’t hear or see, Rudolph is helping to instill compassion and acceptance in the children, Fishman said. “He’s spreading a great message. I will never forget what one child said to me last year, after he hugged Rudolph– ‘I am going to tell my mommy that I want a deaf and blind dog, too.’ “

We’re not taking credit (or blame) for these, just passing them along, as they were passed along to us — the top 10 Pet Peeves of Dogs:
1. Blaming your farts on me … Not funny … Not funny at all.
2. Yelling at me for barking. I’M A DAMN DOG.
3.Taking me for a walk, then not letting me check stuff out. Exactly whose walk is this anyway?
4. Any trick that involves balancing food on my nose. Stop it!
5. Any haircut that involves bows or ribbons. Now you know why we chew your stuff up when you’re not home.
6. The sleight of hand, fake fetch throw. You fooled a dog! Woo hooo! What a proud moment for the top of the food chain.
7. Taking me to the vet for ‘the big snip’, then acting surprised when I freak out every time we go back!
8. Getting upset when I sniff the crotches of your guests. Sorry, but I haven’t quite mastered that handshake thing yet.
9.Dog sweaters. Hello??? Haven’t you noticed the fur?
10.How you act disgusted when I lick myself. Look, we both know the truth. You’re just jealous.
